Another object of the present invention is the provision of a novel keeper for the bolt or a lock of the character referred to which keeper is applicable to different types of doors and can be used with door jambs of various thicknesses.

Another object of the present invention is the provision of a novel lock of the character referred to, provided with a bolt, the projecting part of which is of substantially uniform cross section and which bolt because of its shape cannot be Withdrawn from its keeper by inserting an instrument between the lock case and the keeper.

Another object of the present invention is the provision of a novel bolt particularly adapted for use with locks of the character referred to, having the portion thereof which is adapted to normally project from the lock case of substantially uniform cross section.

Another object. of the present invention is the provision of a. novel, simple, and inexpensive lock of the character referred to, so constructed and arranged that it can be readily converted for use with different types of doors; with doors which swing in as well as'those which swing out; and doors hinged either at. the right hand or the left hand side- The present invention resides in certain details of construction and combinations and arrangements of parts, and further objects and advantages thereof will be apparent to those skilled. in the art to; which the invention relates from the following description of the preferred embodiments thereof described with reference to the accompanying drawings forming a part of this specification, in which similar reference characters designate corresponding parts throughout the several views, and in which:

Although the invention is susceptibleof various modifications and alternative constructions, it is herein illustrated and described in Figs. 1 to 9 inclusive as embodied in a lock applied to a left hand door that opens inwardly and cooperates with a thin door jamb.

Referring to the drawings the lock shown therein comprises a main case or housing A, connected to a back plate 13, mounted on the outside of a door designated generally by the reference character. H. The main caseor housing A encloses the lock mechanism proper including the bolt C, is open at the back, and fits over the back plate B to which it is removably attached in a convenient manner. As shown, the upper end of the back plate 13 has a pair of lugs I2 formed integral therewith, which engage within suitable apertures I3 formed in the inside of the top of the case A, and the lower end of the case A is provided with a screw l4 adapted to be threaded into a suitably tapped aperture in the lower end.

of the back plate B. The construction is such that the screw l4 can be rotated only through the medium of a cylinder lock |5 of conventional construction fixed to the front part of the case A. The lower part of the case A forms a coin or check receptacle, and the lock l5'prevents access thereto as well as to the lock mechanism proper, by unauthorized persons.

The combination keeper and stop shown comprises a member I6 having a rectangular aperture 26 formed in the face thereof adapted to receive the end of the bolt C, an inclined surface 2| leading up to the aperture 26, which inclined surfaces serves the usual purpose of forcing the bolt back into the lock case as the door is closed, and a ledge or projection 22 on the opposite side of the aperture from the inclined surface 2| extending or projecting slightly to the left, as viewed in Figs. 1 and 3. The member I6 is also provided with suitable apertures both above and below the aperture 20 and the inclined surface 2| for the reception of rubber stops or bumpers 23 adapted to be secured therein in a manner hereinafter referred to. While the member l6 may be so constructed that it can be directly secured to the door jamb 24, as shown, it is connected to an angular member 25 which in turn is secured to the door jamb. The part 26 of the member 25 which extends normal to the jamb has a slot or groove formed therein, within which groove the member |6 is located. Flanges 21 on the member 26 project over or in front of a portion of the stops or bumpers 23 and limit the movement of the member I6 relative to the member 25 towards the left, as viewed in Fig. l, by the engagement therewith of ledges 28 on the member I6. The ledges 28 project slightly forward of the rubber stops 23.

The member I6 is adapted to be integrally secured to the member 25 by screws 29 extending through holes in the part 26 of the member 25 and threaded into suitable tapped apertures in the member I 6. The holes in the member 25 may be drilled at the time the lock is installed and their location determined by moving the member l6 relative to the member 26 until the desired final position is attained, depending upon the thickness of the door, and the thickness of the jamb, etc. The screws 29 threaded into the member l6 are slightly elongated so that, when they are in their final position, the ends thereof project slightly into the rubber stops or bumpers 23, thus retaining the same securely in position.

As shown, the bolt C is of rectangular crosssection and is slidably supported within a groove 34 in a member 35, within which groove it is retained by a plate 3'! fixed to the member 35 by screws 38. The screws 38 are also employed to hold the member 35 in position on suitable pads 39 formed integral with the case A. The bolt C is continuously urged towards the left, as viewed in Figs. 5, 6 and '7, that is, in a direction to project the forward end thereof out of the lock case A by a coil spring 46, one end of which is secured to a projection 4| formed integral with the plate 3?, while the other end thereof is secured to a pin 42 fixed to the bolt C and projecting forwardly therefrom, as viewed in Fig. 5, through a slot 44 formed in the plate 31. As previously stated, one of the objects of the invention is to provide a lock which can be readily adapted to either right or left hand doors, and, in regard to this matter, attention is called to the fact that by merely changing the hole in the lock case through which the end of the bolt C projects to the opposite side of the case, the bolt assembly, including the bolt C, the member 35, and the plate 33, etc., can be rotated as a unit to provide a right hand lock.

The bolt C, in addition to being retracted, as the door is closed, by the engagement of the projecting end thereof with the inclined surface 2| of the keeper, may be retracted by any one of the following means: An outside knob or handle 45; an inside knob or handle 46; or a key control. The outside knob 45 is connected to the bolt C through the medium of a coin control, and, in the absence of a key, through the medium of which the key control may be operated, the door can be opened from the outside only upon the deposit or insertion of a check or coin of suitable character or denomination.

In the preferred embodiment of the invention shown, the coin control comprises a disk-like assembly, hereinafter designated the coin carrier, including two spaced plates 41 and 48 connected together by screws 49 and retained in predetermined spaced relation by a member 56 interposed therebetween and held in fixed relation with reference thereto by the screws 49 previously referred to. The coin carrier also includes a member 5| pivotally supported between the disk-like members 41 and 48 by a screw 52. The member 5| normally hangs in a generally vertical position due to gravity, although it is to be understood that suitable spring means may be provided for this purpose, if desired. The members 56 and 5| are so constructed and arranged that with the members 41 and 48 they form a chute 53 for the reception and guidance of a suitable coin or check X for operating the coin control.

The member 5| is pivoted about midway between its ends to the disks 41 and 48 and a little to one side of the center about which the coin carrier is rotatably supported. Slightly below the pivot 52 and on the side adjacent the member 50, the member 5| has formed thereon a seat or semi-circular recess 54 which cooperates with the lower end of the member 5|] to normally retain a coin or check of suitable denomination or character in the lower end of the chute 53. Under normal conditions, rotation of the member 5| in a counterclockwise direction, as viewed in Figs. 5 and 8, is prevented by the engagement of the upper end 55 of the member 5| against a combination coin or check chute and shutter member 56 slidably supported on a rod 57 fixed in the upper end of the lock case A, and by the engagement of the lower end 60 of the same member 5| against a pin 6| (see Fig. 2) projecting from the rear of the bolt C, as viewed in Fig. 5 and extending through a slot or opening in the rear of the member 35 which permits free movement of the pin 6| with the bolt.

The disk member 4! of the coin carrier assembly is fixed to the inner end of what might be called the hub of the outside knob 45 which hub projects into the interior of the lock case through a boss or member 64 and an opening in the front of the case. The member 64 is fastened to the front of the lock case by screws 65 and forms a bearing for the outside knob 45. The inner end or hub of the outside knob 45 is of reduced diameter and forms a shoulder adapted to engage the member 84. This shoulder together with the plate 4'! of the coin carrier secures the knob against movement longitudinally of its axis of rotation.

Rotation of the coin carrier through the medium of the Outside knob 45 is limited by a pairof projections 66 and 6.1: formed integral. with, the member 50' and adapted to engage opposite sides of a raised. pad 53 formed on the inside of they look case A. A coil spring H1 operatively connected to a. projection H on a plate 12 and, t the, upper of the, two screws 49 continuously urges the projection 61 on, the coin carrier into contact with the lower side. of the pad 68;. When the coin, carrier is. in this position the upper end of the coin chute 531 therein aligns with the lower end of a coin chute 1.5 in the combination chute. and shutter member 56 previously referred to, when the latter is in its normal position as shown in Figs. 5 and 8. The upper end of the coin chute T5 in the member 56 is. normally positioned directly underneath a check or coin slot [5 formed in the upper end of the lock case A. The construction is such that under normal conditions, that is, with the parts in the positions shown in Figs. 5 and 8, a coin or check of proper denomination or character inserted in the slot 15 will drop through the chutes l5 and 53 and come to rest in the position shown in the drawmgs.

Rotation of the coin carrier through the medium of the outside handle 45 with a coin in the position shown, will cause the member 5| to rotate with the coin carrier, as a unit, thus withdrawing the bolt 0 through the engagement of the lower end 60 of the member 5.! with the pin 6lcarried by the bolt. In the absence of ,a coin properly positioned in the carrier the member 5| will rotate freely about its. pivot 52 upon rotation of the coin carrier, without having any effect whatsoever on the bolt. With a coin or check properly positioned in the coin carrier the outside knob, which is then operatively connected to the bolt through what has been termed the coin control, can be operated in any desired manner to retract the bolt C any number of times, until the bolt is retracted by one of the other means provided for retracting the same.

When the bolt C is retracted with a coinor check in position by any of the provided means. other than by the outside knob, such as by the projecting end of the bolt C. striking against the inclined surface 2 I. of the keeperlt, as is the case when the door closes behind a person entering therethrough, the pin 6i is withdrawn from engagement with the lower end 6.0 of the member 5|. This allows the member 5!. to rotate about its pivot 52 in a counterclockwise direction, as viewed in Fig. 5, either under the weight of the coin or under the influence of gravity, assuming that the free rotation of the member 5| in the direction mentioned is not obstructed bythe engagement of the upper end 55 with the shuttermember 56 which, under the circumstances stated, would be the case, thus permitting the coin to drop into the bottom of the case A. If desired, the member 5i may be continuously urged in a counterclockwise direction about its pivot 52 by a comparatively light spring if the construction of the member is such that the action of gravity and the weight of the. coin is not sufficient to produce the desired movement to release the coin or check.

In order to prevent the insertion of a second coin before the mechanism has been reset in a manner hereinafter referred to, provision is made for closing the coin slot '55 in the case A by the combination chute and shutter member 58, previously referred to, upon actuation of the. bolt C through the medium of the coin control and on Y the outside knob. As previously s ated; the ember 56 is slidablysupported on; the rod 51 fixed; in the upper part of the lock case A. The member 56 is slid'ably supported on the rod 5! through the medium of a pair of projections H formed integral therewith, and the rod 5'! projects. through suitably aligned apertures formed, in a pair of projections 18 formed by bending; portions. of the plate 12 at an angle to the main; portionthereof. The shutter member 56, is continuously urged towards the right, as Viewed in Fig. 5,, by a coil, spring '59. connected to a projection on the plate 12 and to a pin 8! carried by the shutter 53 and projecting forwardly therefrom, as viewed in Fig. 5, through a slot 8,2, in the plate 12. Movement of the member 56, towards, the; right, as viewed in Fig. 5, under the action of; the spring I9, is limited by a short tubular mem-. ber 83 surrounding the rod '51 and positioned between the. member 56 and the right hand pro- J'ection The upper end 55 of the member 5! is so arranged that normally it engages the right hand side of the member 55 and upon rotation of the coin carrier with a. coin properly positioned therein, moves the member 56 to the left against: the action of the spring #9 to close the slot. 146. In order to retain the shutter or closure member 55 in a position to maintain the coin slot 16.- in the case A closed, after the outside knob. has been released subsequent to the withdrawal of the bolt thereby, a bell crank lever-like springloaded pawl or detent 8,4 is provided. The pawl 84 is pivotally supported about a screw 88. threaded into the plate '52 and the horizontal arm 8:5 thereof has a shoulder d6, thereon adapted to engage behind the pin Has the shutter 56 ap.-. proaches its extreme left hand" position, see Fig- 6,. The pawl 84' is, adapted to be, rotated a clockwise direction, as viewed in Fig. 5,. to reset the shutter, that is, to release the pin 85' from the shoulder 8:6. of the, pawl thus permitting the shutter. to return to its original position under the action of the spring is, upon retraction of the bolt C; through, the medium of either the inside handle it or the key control as will be hereinafter explained. The plate 72-. previously referred to, is, detachably connected to suitable pads formed, in, the upper corners of the look case; A, and in addition to performing the functions already referred to assists in supporting and guiding the shutter 56.

In order to provide visual means for indicating whether the room is, occupied or vacant the front of the loci; case A, is provided with a slot 92, see Fig, 1-, through which suitable notations, suchas, open, and in use" carried by the shutter member it are. visual, depending on whether the shutter is in its normal and inoperative position, that is, its right hand position as viewed in Fig. 5, or in a position, to close the slot 76, which is the left, hand position shown in Fig. 'I.

The inside handlev or knob id is operativelyconnected to a short shaft 93 by being driven onto the reduced upper end 9 thereof, as viewed: in Fig. 3. A boss-like member 95 interposed between the shoulder formed by the reduced end of the shaft-93 and the handle or knob. 46 forms a bearing for the shaft 93 and in turn for the inside knob 45. The member t5 isv adapted to be secured to. the door H by a pair of bosses 9.5 formed integralv therewith which bosses. project into suitable apertures in the door, and by screws 9'? extending through the door from the outside thereof and threaded into suitably tapped apertures in the bosses 96. The outer end of the shaft 93 has a tongue and groove connection with a member I rotatably supported in the plate 48 of the coin carrier and a plate IOI extending across the lock case and secured by screws I02 to suitable pads 68 formed on the inside of the lock case. The member I00 comprises a downwardly extending lever I05 the lower end of which is adapted to engage a pin I06 carried by the bolt 0 and projecting forwardly through the slot '44, as viewed in Fig. 5. The construction is such that upon rotation of the member I00 in a counterclockwise direction, as viewed in Fig. 5, the lever I05 cooperates with the pin I06 to retract the bolt C. A stop in the form of a pin I0! fixed in the plate 31 provides means for limiting the rotation of the lever I05 and in turn the member I00 in the reverse direction.

In addition to the lever I05, the member I00 comprises a pair of upwardly extending arms I08 and I09 the right hand one of which is adapted to engage a flange IIO formed on the vertical arm I II of the pawl 84. Rotation of the member I00 in a counter-clockwise direction, as viewed in Fig. 5, through the medium of the inside knob 46 or the key control, causes the arm I08 to engage the flange H0 and rotate the pawl 84 about its pivot in a clockwise direction. In the event that the pin 8I is caught behind the shoulder 86 on the pawl 84, as is the case when the shutter is in its operative position as shown in Fig. 7, the pin 8| is released, permitting the shutter 56 to be returned to its normal position under the action of the spring IS.

The various parts are so constructed and arranged that as the bolt is retracted from the keeper, through the medium of the coin control, the shoulder 86 on the pawl 84 engages behind the pin 6| before the bolt has been entirely retracted or released. This prevents any possibility of a person opening the door through the medium of the coin control without the coin slot I6 in the lock case being maintained closed by the shutter 56 after the knob is released. The upwardly extending projection or arm I08 of the member I00 also engages the flange I I0 on the downwardly extending arm III of the pawl 84 before the bolt has been entirely withdrawn from the keeper through the medium of the inside handle 46, which assures the closure member 56 being returned to its original position upon the room being vacated.

In order that the door to which the lock is applied may be opened from the outside by an attendant or other authorized person without the deposit of a check or coin, provision is made for rotating the member I00 and, in turn, the levers I05 and I08 from the outside of the door through the medium of a key control. As shown, this key control comprises a cylindrical member I I4 slidably and rotatably supported in a suitable counterbore H5 in the outside knob 45. Opposite ends of the member II4 are reduced and square in cross-section. The outer square end H6 is adapted to receive a suitable key formed on the order of a socket wrench, and the inner square end I I1 is adapted to fit into a square hole or socket H8 formed in the end of the member I00. The member H4 is normally retained in a retracted position, that is, in the position shown in Fig. 2, by a spring I20 interposed between the lock case A and a shoulder on the member 4 formed by the reduced portion I I1 thereof. The square end I I1 is adapted to be projected into the square aperture I I8 formed in the member I00 and the member I00 rotated thereby independently of the outside knob through the medium of a suitable key. As previously pointed out, rotation of the member I00 in a clockwise direction as viewed in Fig. 1 will withdraw the bolt 0 and reset the shutter member 56 in the event the latter is in its closed position. The tongue and groove connection between the shaft 93 and the member I00 permits the lock case and the mechanism assembled therewith to be removed as a unit without disturbing the back plate and the inside knob.

It is thought that the operation of the device will be apparent from the foregoing description thereof. Sufiice it to say that a coin or check X of suitable denomination or character inserted through the coin slot I6 in the lock case will be retained in operative position in the coin carrier between the seat 54 formed on the lever 5I, and the lower end of the member 50 until the bolt is withdrawn by one of the means provided other than through the medium of the coin control. This assures the person desiring entrance to the room access thereto upon turning the outside knob a sufficient amount irrespective of how the outside knobis manipulated. As previously stated, the position of the pin 8| relative to the catch 8i: on the pawl 84 is such that the shutter member 56, or rather the pin 0| carried thereby, is caught by the pawl before the bolt has been entirely withdrawn from the keeper so as to prevent any possibility of a person entering the room while leaving the lock in condition for the reception of a second coin. The distance between the seat 54 on the lever 5| and the lower end of the member 50 is preferably such that a check of improper character or a coin of incorrect denomination will not be retained therebetween but will drop through the coin carrier into the receptacle at the base of the lock case without permitting actuation of the lock.

As previously stated, one of the objects of the present invention is to provide a lock which is readily applicable to either right or left hand doors, and, for this purpose, the various parts are made reversible or symmetrical. As referred to above, the bolt assembly comprising the bolt C, the member 35, the plate 3?, etc., can be reversed by merely changing the aperture through which the bolt projects to the opposite side of the case. The coin carrier can be reversed by merely changing the member 50, the lever 5|, and the spring I0 to the opposite sides. Suitable apertures are provided in the various members to make this change possible. For example, the holes for the screws 49 and 52 are duplicated on opposite sides of the center line and the projection II on the plate I2 is duplicated on opposite ends of the plate. The duplicate parts are designated by the same reference characters but with a prime mark afiixed thereto.

The pawl 84 is preferably manufactured flat and the flange IIO thereon bent one way or the other at the time of assembly, depending upon whether it is to be used in a left hand lock as shown or in a right hand look. In the case of a right hand lock, the arm I09 on the member I00 engages the flange on the pawl 84 to reset the shutter 56 in a manner similar to that in which the arm I08 cooperates with the flange H0 in the left hand lock shown. In order to reverse the closure or shutter 56, it is merely necessary to move the sleeve 83 and the spring 19 to the other side. The notation in use appears at opthose with thin jambs. 7 shown in Figs. 10 and 11 in which the parts here- 'cured to the inside face thereof.

*coi-n tray in the bottom o? the lock case for the posite sides of the word open? from which it follows that the notation in use appears in the slot 92 of the lock case irrespective of Whether the shutter moves to the right, as viewed in Fig.

1, for a left hand lock, or to the left as would be the case with a right hand lock,

The present lock is also readily applicable to installations having thick door jambs as well as Such an installation is tofore referred to are designated by the same reference characters. In this event, the keeper proper, in other words, the member 16, is removed from its supporting member and attached directly to the face of the door jamb 150. In the molding. The clips I22 are held in position by screws I25 extending through suita le apertures formed in the flanges F23. The member 15 is secured to the door jamb E by screws F28.

Figs. 12 and 13 show the lock as applied to a left hand door which opens out. In this event the keeper comprises a member 130 bolted to the outside face of the jamb Hi and a stop I32 se- The keeper I351 is provided with a rectangular aperture 133 similar to the aperture 28 in the keeper l8, and an inclined surface 5341 in frontof the slot 133which serves the usual purpose of retracting the bolt 0 as the door is closed behind a person entering or leaving the room. The stop I32 includes a rectangular rubber member I35 secured in 'a suitable groove, which rubber member c'o n stitutes the stop proper.

From the foregoing description of the preferred embodiments of my invention it will be apparent that the objects of the invention heretofore enumerated have been accomplished, and that there has been provided a simple, reliable, easily assembled lock which cannot be operated is readily applicable to either right or left hand 'doors and to installations having either thin or thick door jambs. Entrance cannot be obtained by way of the coin control without setting the "shutter against the insertion of a second coin.

In like manner, it is impossible to open the "door from the inside without resetting the shutter. The outside knob can be manipulated any number of times and in any manner without releasing the coin or check in the coin carrier so long as the bolt is not retracted independently of the coin control. The particular shape of the members 53 and 5] shown forms a sinuous path for the coin or check, which together with the particular location of the pivot 52, prevent the possibility of retracting the bolt by means of an instrument inserted through the coin slot at the top of the case.

While the preferred embodiments of the invention have been herein illustrated and described in considerable detail, the invention is not limited to the particular construction shown. Numerous changes in the construction shown, all within the scope of the invention, will suggest themselves to those skilled in the art to which the invention relates, such change including the use of a character referred to, the combination of a housing having a slot for the reception of a coin or check, a bolt slidably supported in said housing and normally projecting therefrom, means for continuously urging said bolt in a direction t'o project the same from said housing, means for retracting said bolt, said means including a "coin orcheck carrier rotatably supported 'insaid'housing, means for rotating 'said'coin or check carrier from without said housing, a member pivotally "supported by said coin or check carrier, means foperatively connecting said member with said bolt for limiting movement of said member relative to said bolt in a direction to retract said bolt, said member being normally retainedby said 'bolt in a position to retain a coin or check in said coin or check carrier in position to limit movement of said member about its pivot relative to said coin or check carrier in the direction in which said first-named means acts thereon upon rotation of said coin or check carrier, and means for retracting said bolt independently of said coin or check carrier whereupon said member is not retained by said bolt in said position to retain a coin or check in said coin 'or check carrier.
